Like I said, it makes no sense mathematically or genealogically. How do you calculate who is "fully black" when a majority of ADOS (with two black parents) have the blood of rapist slavemasters coursing through their veins? Why do y'all obsess about the race of people's parents? Like, why do you stop just at parents when most black people probably have some non-black in them going back a generation or two? Why don't you count that?
(Let's not get into the fact that this whole notion floats on the false idea that race is a biological reality to begin with)
This obsession with people's genes and racial purity bugs me a lot, because it sounds EXACTLY like the kind of rhetoric that was circulating in Germany back in the 1930s when a dude with the initials A.H. was in control over there...
